We can not update iph->daddr in ip_options_rcv_srr(), It is too early. When some exception ocurred later (eg. in ip_forward() when goto sr_failed) we need the ip header be identical to the original one as ICMP need it.

Now that we enable multiqueue by default the ehea driver is using quite a lot of memory for its buffer pools. With 4 queues we consume 64MB in the jumbo packet ring, 16MB in the medium packet ring and 16MB in the tiny packet ring. We should only fill the jumbo ring once the MTU is increased but for now halve it's size so it consumes 32MB. Also reduce the tiny packet ring, with 4 queues we had 16k entries which is overkill.

When transmiting a fragmented skb, qlge fills a descriptor with the fragment addresses, after DMA-mapping them. If there are more than eight fragments, it will use the eighth descriptor as a pointer to an external list. After mapping this external list, called OAL to a structure containing more descriptors, it fills it with the extra fragments. However, considering that systems with pages larger than 8KiB would have less than 8 fragments, which was true before commit a715dea3, it defined a macro for the OAL size as 0 in those cases. Now, if a skb with more than 8 fragments (counting skb->data as one fragment), this would start overwriting the list of addresses already mapped and would make the driver fail to properly unmap the right addresses on architectures with pages larger than 8KiB. Besides that, the list of mappings was one size too small, since it must have a mapping for the maxinum number of skb fragments plus one for skb->data and another for the OAL. So, even on architectures with page sizes 4KiB and 8KiB, a skb with the maximum number of fragments would make the driver overwrite its counter for the number of mappings, which, again, would make it fail to unmap the mapped DMA addresses.

Since linux 2.6.26 (commit c6aefafb : Add IPv6 support to TCP SYN cookies), we can drop a SYN packet reusing a TIME_WAIT socket. (As a matter of fact we fail to send the SYNACK answer) As the client resends its SYN packet after a one second timeout, we accept it, because first packet removed the TIME_WAIT socket before being dropped. This probably explains why nobody ever noticed or complained. Reported-by: NJesse Young <jlyo@jlyo.org> Signed-off-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NDavid S.

Prevent tracing of preempt_disable() in get_cpu_var() in kvm_clock_read(). When CONFIG_DEBUG_PREEMPT is enabled, preempt_disable/enable() are traced and this causes the function_graph tracer to go into an infinite recursion. By open coding the preempt_disable() around the get_cpu_var(), we can use the notrace version which prevents preempt_disable/enable() from being traced and prevents the recursion.

Dummy, non-zero definitions for HPAGE_MASK and HPAGE_SIZE were added in 51c6f666 ("mm: ZAP_BLOCK causes redundant work") to avoid a divide by zero in generic kernel code. That code has since been removed, but probably should never have been added in the first place: we don't want HPAGE_SIZE to act like PAGE_SIZE for code that is working with hugepages, for example, when the dependency on CONFIG_HUGETLB_PAGE has not been fulfilled. Because hugepage size can differ from architecture to architecture, each is required to have their own definitions for both HPAGE_MASK and HPAGE_SIZE. This is always done in arch/*/include/asm/page.h. So, just remove the dummy and dangerous definitions since they are no longer needed and reveals the correct dependencies. Tested on architectures using the definitions with allyesconfig: x86 (even with thp), hppa, mips, powerpc, s390, sh3, sh4, sparc, and sparc64, and with defconfig on ia64.
